    Hi Graham , I hope all is going well there . Can I ask what you used to insulate under the metal roof ?

    Ageed. Solar in Pinas with high energy costs and abundance of sunshine must be a no brainer. Was the grid tie installed by professionals? If so what make/model of controller and inverter was used?

    I have two cows in the back yard. Plenty of methane to self-power the whole house.

    You make a good point and I think the same every time we drive by that house here. Why do they both constantly spin on hot days
    with no noticeable breeze or wind? Ive looked at them at hardware stores here and none of them are powered electrically. They are both installed pretty high up on the ridge.. On that scorching hot red lead roof,I just assumed that the convection currents were strong enough to make them spin.

    When it gets hot again here,I`ll take some footage of them.

    The convection currents are strong enough to make them spin, it's just that with a bit of wind they could spin more and increase the airflow over what you get with natural convection, depending on the design.

    The spinning is the result of convection but if convection alone made it spin faster and faster spinning made it pull more air then it would get faster and faster until it destroyed itself because it would have a magical infinite source of energy for the spinning :)

    They are venting and the vent alone will certainly help cool a place down a bit, plus these will help to some extent to stop insects and other creatures working their way back down the vent as long as they are moving I guess, Ana blocked up our kitchen vent to stop insects getting in at one point, as if it wasn't hot enough already, madness :frust:

    Industrial versions of these things are often connected to a large fan inside the building to utilise the wind to provide additional extraction and usually to encourage smoke and other industrial waste gases to go up the vent.

    Electricity IS dear here, compared with other Asian countries, but my overall fuel bill is still half what it was when I lived alone in my house in the UK, as opposed to here, with 3 adults and a child.

    ... And then there's the booze... and the beaches, and the birds. :like:

    I would not normally clip a photo from a photographer's site but in this case, for the joke, this chap has the absolute best photos and I have huge respect this man, Romy Ocon.

    He is a truly great Nature Photographer and he's Filipino, check out his gallery in the link I supply above the picture.

    It appears that plain vents that don't have a turbine don't vent due to backdraft if there is any wind.
    and this is why they work

    We have massive electricity bills here, there are 5 air cons and when the house is
    full of Filippinos they are all on it pulls down the voltage in the village. The bills are OK when there's just the 2 of us, hopefully they will go home soon.
    I had the solar guy round and he said it would be too expensive to install solar and to buy a line fail diesel generator which would cover brownouts and can be used without the mains.
    I like the idea of the rotary ventilators, but worry what happens when there is a typhoon, we just caught the edge of the last one, I can see them self destructing. the roof guy is coming so I will talk to him about the ventilators and some insulation in the loft. I'll let you know the outcome.    ​

    Would that mine would do that, however at least I managed to sign up for Meralco's online billing system again a couple of days ago, it took them nearly a year to replace a simple web site that worked fine and had serviced its customers for the previous 10 years perfectly well and during that replacement time for the last year nothing worked :frust:

    This time I at least signed up with an email address for Ana that lives on my own domain and with my own Philippine phone number so I have full control of the Meralco bill for once and I might even be able to pay direct via Visa or Mastercard, I'll try that next month and see what the extra card charges are.

    This is my misery :D

    April and May I am perfectly happy to admit that was me, it would have been a lot less if I had not been there :)

    Live without the aircon, it's not that hard, you will get used to it and like it in time, honestly.

    It's only really needed at night and then only if your ventilation is poor as the temperature drops a lot at night.

    We used 126 kWh during the last monthly billing period. About average. We have at least 2 fans going 24 hours a day.

    I can't afford much more, as I'm a poverty-stricken OAP... with better things to spend my pittance on. :like:

    It's cold and wet here today. Tucked up in bed with the central heating on.

    It's my sister's birthday today. She lives in Durham City... and has just sent me pics of the SNOW up there. :eek:

    Getting dark here now, but earlier it was around a pleasant 35C, with a bit of a (rare) strong breeze blowing. :like:

    Thinking of getting a Pure sine wave inverter for brownouts we keep getting, my Desktop is struggling to boot up. Then later on maybe get some solar panels and Batteries, just a small set up at first then add more panels and batteries.

    Get a surge protector first or a UPS to protect the PC, laptops are to some extent protected by their own battery and the transformer that charges them but even they could be damaged by some of the brown outs I've seen in the Philippines.
